The chuck 2231, thetapered split clamping ring 2232 and the locating plate 2233 each have acenter through hole 22311, 22321, or 22331. The locating plate 2233 hastwo mounting holes 22332 at two sides of the center through hole 22331.During installation, the tapered split clamping ring 2231 is partiallyinserted through the center through hole 22331 of the locating plate2233, and then the tapered split clamping ring 2231 and the locatingplate 2233 are attached to one coupling block 224 corresponding to oneend of the center axle hole 2241, and then the two mounting holes 22332of the locating plate 2233 are respectively fastened to respectivelocating holes 2242 of the coupling block 224 at two sides of the centeraxle hole 2241 of the coupling block 224 by fastening means, forexample, screws (not shown), and then the chuck 2231 is fastened to thefront end of the tapered split clamping ring 2231 and stopped at oneside of the locating plate 2233 opposite to the coupling block 224. Theadjustment rods 222 each have one end inserted through the centerthrough hole 22311, 22321, 22331 of one of the locking devices 223 andthe center axle hole 2241 of each of the coupling blocks 224 and theother end provided with a pivot hole 2221. The holding down bar 221 ispivotally connected between the pivot holes 2221 of the adjustment rods222. The axle 227 is inserted through the second horizontal axle hole233 of one bearing blocks 23 with the two distal ends respectivelyfastened to the coupling hole, referenced by 2244, of each of thecoupling blocks 224, having two annular locating grooves 2271respectively extended around the periphery near the two distal endsthereof. The two spacer barrels 226 are respectively sleeved onto thetwo distal ends of the axle 227 and stopped at the two opposite lateralsides of the respective bearing blocks 23. The retaining rings 225 arerespectively fastened to the annular locating grooves 2271 of the axle227 to secure the spacer barrels 226 to the axle 227, each having aradial split 2251 by which the respective retaining ring 225 can easilybe fastened to the annular locating groove 2271 at one end of the axle227, and two mounting holes 2252 respectively fastened to respectivelocating holes, referenced by 2243, of one coupling block 224 byfastening means, for example screws (not shown).

In the aforesaid locking devices 213, 223, the chucks 2131, 2231 can berotated forwards or backwards to compress or release the respectivetapered split clamping rings 2232, so as to further lock the bearingblocks 23 to the axle 212 and the adjustment rods 222 to the couplingblocks 224 or to unlock the bearing blocks 23 from the axle 212 and theadjustment rods 222 from the coupling blocks 224.

Referring to FIG. 6 and FIG. 1 again, the base 10 has a rail 115protruded from the top wall thereof and extended in X-axis direction,and three mounting grooves 116 respectively formed in the two distalends and middle part of the rail 115. The three axle holders 211 of thehorizontal adjustment mechanism 21 are respectively fixedly fastened tothe mounting grooves 116, thereby securing the horizontal adjustmentmechanism 21 to the base 10. Further, the bearing blocks 23 each have abottom sliding groove 234 respectively coupled to the rail 115 of thebase 10 to guide movement of the bearing blocks 23 along the rail 115.

Referring to FIGS. 7 and 8, by means of the wheels 13 of the base 10 andthe handle 12, the user can push the pet's dressing cart 1 to thedesired place. After the pet's dressing cart 1 has been moved to thedesired place, the stands 142 of the front and rear stand assemblies 14are respectively turned from the non-operative position above the bottomside of the wheels 13 to the operative position below the bottom side ofthe wheels 13 to support the pet's dressing cart 1 on the floorsteadily. The adjustment unit 20 is then adjusted subject to the size ofthe pet. At this time, loosen the chucks 2131.to release the taperedsplit clamping rings 2132 from the axle 212, and then move the bearingblocks 23 along the axle 212 relative to each other to adjust the pitchbetween the bearing blocks 23, and then fasten up the chucks 2131 again.After adjustment of the horizontal adjustment mechanism 21, keep the petstand on the bearing blocks 23 with the belly supported on the inwardlycurved top bearing portion 235 of each of the bearing blocks 23, andthen adjust the holding down mechanisms 22 is adjusted to hold down thelegs of the pet. By means of loosening the chucks 2231 to release therespective tapered split clamping rings 2232 from the respectiveadjustment rods 222, the adjustment rods 222 can be movedforwards/backwards relative to the respective coupling blocks 224 toadjust the elevation of the respective holding down bars 221. Afteradjustment, the chucks 2231 are fastened up again to lock the adjustmentrods 222 to the coupling blocks 224. Preferably, each holding down bar221 is covered with a sponge or rubber covering so as not to hurt thepet's legs.
